GH-3900RSU™

Electronic Standby Instrument Systems

The thinnest and widest remote-mounted standby for business and commercial aircraft

At only 1.5 inches deep, the L3 GH-3900RSU™ Electronic Standby Instrument System (ESIS) is the thinnest electronic standby instrument available for business, regional and commercial aircraft and helicopters. Highlighting the system’s design is a Remote Sensor Unit (RSU) which enables the 4.2-inch (diagonal) landscape display to be installed virtually anywhere on the panel. The GH-3900RSU ESIS is designed to meet the needs of Part 23 (Class III & IV), Part 25 aircraft and Part 27 and Part 29 helicopters.

Two pieces mean one flexible solution

The two-piece design of the GH-3900RSU gives aircraft designers and avionics installers the greatest possible flexibility when it comes to the display’s location. Because the RSU houses the rate/level sensors, air data transducers and optional accelerometers, the panel display needs to be only 1.5 inches deep.
